HEATING DEVICE FOR REPAIRING PAVEMENT STRUCTURE HEAD SECTION, AND REPAIRING METHOD USING HEATING DEVICE

PROBLEM TO BE SOLVED: To do work safely and efficiently by providing unit frames connectable to each other, heating means fittable to the unit frames, and a heating source. SOLUTION: Unit frames 2a, 2b, 2c, 2d are connected in response to the required heating width of a pavement structure head section to be repaired, and heating means 3a, 3b, 3c, 3d are fitted to the unit frames 2a-2d. A heating source 8 is connected to the heating means 3a-3d via flexible pipes 9a, 9b and rigid and nonbending pipes 10a, 10b to form a heating device 1 for repairing the pavement structure head section. A sealing material is inserted into the cracked portions of a pavement body at the time of execution, and the cracked portions are heated while the heating device 1 is towed by a work vehicle. An asphalt mixture is supplied around the cracked portions as required, and it is heated, fused, and rolled together with the sealing material. The pavement body can be repaired more safely and efficiently.
